Summary: The study showed that optimizing with daily N2O emissions can improve model accuracy, and the posterior distributions of key parameters provide a reference range for future model improvement and applications. The results also indicated a potential to optimize nitrogen fertiliser rate in order to reduce N2O emissions while maintaining crop yield in an irrigated wheat-maize rotation system.

Summary: The co-application of straw and different types of nitrogen (N) fertilizers affects N transformation and N2O emissions in acid soil, with the form of N fertilizer playing a crucial role in N2O accumulation. The alteration in soil pH has an impact on N transformation processes and subsequent N2O emissions.

Summary: This study investigated N2O + N-2 losses in response to different N fertilizer rates on tropical sugarcane farms in Australia. The results showed that N2O + N-2 losses increased non-linearly with increasing N fertilizer rates. This study provides a method to extrapolate denitrification measurements at both temporal and spatial scales.

Summary: This study evaluated how tetracycline affects N2O emissions and the abundance of denitrifiers in fertilized soil. The results showed that NH4NO3 in fertilized soil increased N2O emissions and abundance of AOB, while tetracycline did not mitigate these emissions. However, higher doses of tetracycline may have a positive effect on reducing N2O emissions in the long term.

Summary: Recent studies have shown that the application of biochar to soil can improve soil properties and reduce N2O emissions, especially in cases of repeated application, higher application rates, and higher levels of N fertilization. Initial and repeated biochar applications have proven to be effective in enhancing soil quality and mitigating greenhouse gas emissions, particularly by increasing soil pH.

Summary: The study estimated field-scale inferred N-2 emissions by comparing data of field N2O emissions and laboratory-measured N2O/(N2O + N-2) ratios. Results showed that field-scale inferred cumulative N-2 emissions were higher than laboratory-measured cumulative N-2 emissions, indicating the importance of estimating N-2 emissions at the field-scale in agricultural soil. Linear relationships were observed between N fertilizer rates and both field and laboratory cumulative N2O and N-2 emissions, suggesting that climate change mitigation could be achieved by optimizing N fertilization rates. Positive and negative relationships between soil-environmental parameters and N2O, N-2 and their N2O/(N2O + N-2) ratios at field and laboratory scale indicate their heterogeneous roles in N2O formation and reduction processes.

Summary: A three-year study was conducted to improve wheat productivity and reduce N2O emissions in soils with varying nitrogen supply. The findings suggest that adjusting nitrogen fertilization timing and monitoring spectral properties during growth stages can effectively enhance grain yield and protein content. Rescheduling nitrogen topdressings and sustaining nitrogen supply till grain filling stages were key strategies in achieving higher yields and mitigating greenhouse gas emissions.

Summary: Greenhouse vegetable production in China often involves excessive use of nitrogen fertilizers and flood irrigation, leading to soil degradation and spread of soil borne diseases. Anaerobic soil disinfestation (ASD) is applied as a countermeasure, but the use of organic C sources and manure in this process can result in significant greenhouse gas emissions and nitrogen leaching. Optimizing irrigation schemes and advising against the use of chicken manure during ASD period can help reduce environmental losses and improve sustainability in greenhouse vegetable production.

Summary: The study showed that the specific surface area of biochar is related to nitrogen emissions and the abundance of nitrogen-metabolizing microbial genes. Biochars with larger specific surface areas can reduce nitrogen emissions, recruit N2O-reducing microbes, and upregulate nitrogen-fixing, nitrifying, and denitrifying genes.

Summary: The combination of chemical nitrogen fertilizer with crop straw in a rice system not only reduces nitrogen use efficiencies (NUEs), but also leads to environmental problems. Adding straw improves NUE and reduces Cd distribution in rice, but it also affects Cd accumulation and alters bacterial community structure. Our study highlights the trade-offs between straw incorporation with N fertilizer in eliminating potential Cd toxicity, increasing fertilizer-N use efficiencies, and providing feasible agricultural management.
